NCT01975389
This study evaluates the PCSK9 inhibitor, Bococizumab (PF-04950615;RN316), compared to placebo, in reducing the occurrrence of major cardiovascular events, including cardiovascular death, myocardial infarction, stroke, and unstable angina requiring urgent revascularization in high risk subjects who are receiving background lipid lowering therapy and have cholesterol laboratory values of LDL-C \>/= 100 mg/dL (2.6 mmol/L) or non-HDL-C \>/=130 mg/dL (3.4 mmol/L).
NCT00510198
The purpose of the PRECEDE-HF study is to collect data to compare patients whose heart failure is managed using Cardiac Compass with OptiVol (which is a tool in the device that records information about the heart that doctors can use to help treat their heart disease) combined with standard treatment methods (Access Group) to patients whose heart failure is managed by standard treatment methods only (Control Group). This comparison will show if the additional monitoring provided by Cardiac Compass with OptiVol delays the time patients are first admitted to hospital for heart failure or delays the time to death.
NCT01638897
The purpose of this study is to evaluate long-term performance of the DF4 Connector System. This evaluation is based on the number of DF4 lead-related complications occurring during the study compared to the number of leads enrolled in the study. The DF4 systems will be followed for 5 years after implant. This study is required by FDA as a condition of approval of the DF4 Connector Systems. This study is conducted within Medtronic's post-market surveillance platform.
NCT01663402
Primary Objective: To compare the effect of alirocumab with placebo on the occurrence of cardiovascular (CV) events (composite endpoint of coronary heart disease (CHD) death, non-fatal myocardial infarction (MI), fatal and non-fatal ischemic stroke, unstable angina (UA) requiring hospitalization) in participants who experienced an acute coronary syndrome (ACS) event 4 to 52 weeks prior to randomization and were treated with evidence-based medical and dietary management of dyslipidemia. Secondary Objectives: * To evaluate the effect of alirocumab on secondary endpoints (any CHD event , major CHD event, any CV event, composite of all cause mortality/non-fatal MI/non-fatal ischemic stroke, CHD deaths, CV deaths, all cause mortality). * To evaluate the safety and tolerability of alirocumab. * To evaluate the effect of alirocumab on lipid parameters.
NCT01076348
Safety and effectiveness will be summarized for the model 4965 lead. This study was conducted within Medtronic's System Longevity Study (SLS).
NCT01786993
This IDE study is a prospective, randomized, double-blind, multi-center clinical study to evaluate the safety and efficacy of patient treatment with MPP compared to patient treatment with standard BiV pacing at 9 months. The study will be conducted at a maximum of 50 investigational centers located in the United States. A maximum of 506 subjects implanted with the Quadripolar cardiac resynchronization therapy device (CRT-D) system will be enrolled in the study.
NCT01500434
The purpose of this study is to evaluate the safety and effectiveness of the PROMUS Element™ Everolimus-Eluting Coronary Stent System for the treatment of patients with up to 2 de novo atherosclerotic coronary artery lesions. The lesions can be longer than average-sized.
NCT01498692
The purpose of this study is to evaluate the safety and effectiveness of the PROMUS Element™ Everolimus-Eluting Coronary Stent System for the treatment of patients with up to 2 de novo atherosclerotic coronary artery lesions. The lesions can be located in vessels that are smaller than average-sized.
NCT00746356
This study is a prospective, non-randomized, multi-center clinical trial that will assess the safety and effectiveness of investigational models of the Promote™ RF CRT-D and Current™ RF ICD devices. These new ICD and CRT-D devices have new features that allow the device to periodically check how much energy is needed to pace a patient's heart and to automatically adjust the amount of energy used to pace the heart.
NCT00916929
To demonstrate the safety and effectiveness of the Impedance Monitoring Feature in St Jude Medical cardiac devices.
NCT01993862
The purpose of this study is to determine whether it is safe to send patients home from the hospital on the same day following an implantable cardioverter defibrillator (ICD) implant.
NCT00303979
The purpose of this study is to characterize current management of patients with either heart failure or prior myocardial infarction and left ventricular dysfunction and to assess the effect of education, specific clinical guidelines, reminder systems, comprehensive disease state management tools, benchmarked quality reports, and academic detailing on the use of evidence-based heart failure therapies in cardiology practices. This study is a quality improvement initiative that is being conducted through review of patient records.
NCT02656329
This is an event-driven Phase IIIb, multicentre, randomised, clinical study to demonstrate the efficacy of AdreView™ imaging for appropriately guiding the decision of implantable cardioverter defibrillator (ICD) implantation, in New York Health Association (NYHA) class II and III heart failure participants with 25%\<=left ventricular ejection fraction (LVEF)\<=35%, and in particular, for identifying participants who are at low risk for sudden cardiac death and who would not benefit, or may suffer harm, from implantation of an ICD device.
NCT01587651
This is a Phase 4, multicenter, open-label (blinded Pharmacodynamic PD results), randomized, 3-arm, parallel-design study of subjects with stable Coronary Artery Disease CAD. This study will compare the PD effect of prasugrel 10 mg QD (once-daily) maintenance dose with ticagrelor 90 mg BID (twice daily) maintenance dose in subjects with stable CAD who have previously received ticagrelor loading does (LD) and maintenance dose (MD)..
NCT01832610
Patients will be approached to participate in this PAS after the HeartWare® Ventricular Assist System receives PMA approval for the indicated use as a bridge to cardiac transplantation.
NCT02470312
The goal of this registry/observational study is to collect data on the clinical utility of MediGuide™ system in cardiac resynchronization therapy (CRT) implantation and electrophysiology (EP) procedures.
NCT02548455
The primary intent of this study is to assess the safety of the model 1457Q Quartet LV lead at 3 months in a patient population indicated for cardiac resynchronization therapy.
NCT01323153
This double-blind, randomized, placebo-controlled, multi-center study will evaluate the safety and efficacy of dalcetrapib in patients hospitalized for an acute coronary syndrome (ACS). Treatment will be initiated within 1 week after the ACS. Patients will be randomized to receive dalcetrapib 600 mg as daily oral doses or matching placebo. The anticipated time on study treatment is 20 weeks.
NCT02053038
Narrowing of coronary arteries interferes with blood flow and can cause chest pain. But patients may have more than one narrowing and studies have shown that not all narrowings need to be treated. To identify the narrowings that need treating cardiologists sometimes quantify the extent of the narrowing by measuring fractional flow reserve (FFR, the ratio of the pressure in the aorta to the pressure downstream of the narrowing).This technique requires the administration of drugs that add cost and time to the procedure and in some countries are simply unavailable. As a result despite the clear health and healthcare costs benefits of FFR its use is limited to less than 5% of procedure. We have developed a new technique called the instantaneous wave-free ratio (iFR) that does not require the administration of drugs for its accurate assessment. It has been approved for use in this indication. This study aims to compare clinical outcomes of patients whose treatment has been guided by iFR to those whose treatment has been guided by FFR. If iFR is found to provide the same clinical outcomes as FFR its adoption will permit the clear benefits of this approach of identifying the coronary narrowings that really need treatment to be applicable to a much larger patient population and further improve healthcare costs.
NCT01826019
The overall objective of the HOPE-4 Phases (HT and CVD) is to develop, implement and evaluate an evidence-based, contextually appropriate programme for cardiovascular disease (CVD) risk assessment, treatment and control involving: (1) simplified algorithms implemented by non-physician health workers (NPHW) and supported by e-health technologies (tablets programmed with decision and counselling support software); (2) initiation of evidence-based cardiovascular (CV) medications and (3) treatment supporters to optimize long-term medication and lifestyle adherence.
